Long-term mortality in patients diagnosed with cancer during pregnancy or postpartum

Outcomes among patients with pregnancy-associated cancers, diagnosed during pregnancy or 1-year postpartum, other than breast cancer have received relatively little research attention. High-quality data from additional cancer sites are needed to inform the care of this unique group of patients. A population-based retrospective cohort study in three Canadian provinces found that among premenopausal women with cancer, there was a higher risk of death due to pregnancy-associated cancer than there was from cancer remote from pregnancy. However, these results varied across cancer sites. The authors conclude that pregnancy-associated cancers may have increased risk of mortality, though not all cancer sites present the same risk elevation.
